We are looking for wiring recommendations. We would like to have each ski hill that we time at to have the same system. We want wire that can be rolled up and move to another run without breaking and heavy enough gauge to make connections without breaking. We want the outside of the cable to be tough enough that it can be stepped on without damage. I am not sure we need four pairs of wires, it seems like two would be enough. We are also looking for recommendations for banana type junction boxes where these outdoor cables can be hard wired into. Our goal is to arrive and just plug in without all the testing and trouble shooting we always have to do, and avoid the delays associated with improvised connections that fail during a race. What do you recommend?
